Timeline of events in the anime

A map of the Hoenn, Johto, Kanto, and Sinnoh regions in the anime; locations of movies are deliberately marked, and labeled Pokémon are positioned in relation to the locations of certain episodes.

This is a chronological list of significant events in the anime and the episodes which they occurred in, or, for events which happened outside the series, where they happened in relation to the episodes.

Kaiser reports the existence of a Dratini in the Safari Zone. Thousands of people came to get the rare Pokémon, which literally destroys the Safari Zone in the process. Since then, they only allow Safari Ball there. (EP035)

Lola leaves Pewter City out of boredom, leaving her children in the hands of her oldest son, Brock. (EP005)

In the dub of EP005, Flint says Lola died at this point, rather than leaving. In subsequent episodes where Lola appears, the dub follows the original with Lola leaving home and leaving everything in Brock's care.

Serena is sent to Pallet Town in Kanto against her will, to attend a summer camp hosted by Professor Oak. She gets lost in a nearby forest, and hurts her knee, where she meets Ash and is rescued and led back to the camp by him. (XY007)

Clemont befriends a Shinx when studying in an academy specializing in Electric-type Pokémon. (XY048)

Clemont modifies the program of Clembot and leaves it in charge of the Gym, and he and Bonnie continue traveling with Ash and Serena.

Despite the badge restriction no longer being an issue, Ash decides to wait until he's acquired three more Gym badges before challenging the Lumiose Gym, and Clemont agrees to meet the challenge himself when the time comes.
